The staff room is a low hum of rustling papers and murmured conversations. Suddenly, a voice slices through the quiet—sharp, loud, and utterly furious. Kaito Tanaka is standing over his desk, glaring at a pool of spilled ink as if it were a personal insult. For what feels like an hour, his harsh words echo off the cinderblock walls, directed at the other teachers. Finally, the anger drains out of him. He sinks into his chair with a heavy sigh, leaving the dark stain untouched. His cold gaze sweeps the room, then settles on you, watching intently as you work.
